I have filed applications in Germany Dec. 2, 1929, Ser. No. Kl1'. ,?7l and Germany, May 10, 1930, Ser. No. 3 lg-Kel2/30.

My invention relates to improvements in couch-beds having within the main frame a mattress with the feather beds thereon ready for use and provided with openings between the main frame and the mattress for ventilating and airing the bedding during the day time.

The object of my invention is to provide a piece of furniture not showing that it can be converted into a bed, permitting hygienic keeping of the bedding and leaving no comforts to be desired when used as bed.

With these and other objects in view the invention consists of certain new and useful features of construction and combination as hereinafter described and particularly point- 'ed out in the appended claims and in the drawing forming part of this specification.

Similar figures of reference indicate corresponding parts in all the views.

Fig. 1 shows a side view of the whole piece of furniture, the top part being raised. Fig.

2 is a front view of the same. Fig. 3 is a sectional view in the line 3-3 in 2, the piece of furniture being used as couch. Fig. 4 is a sectional view in the line @4 in Fig. 1, also in use as couch. Fig. 5 is a top View the piece of furniture being used as couch. Fig. 6 shows a part of the construction when the piece of furniture is used as couch. Figs. 710 are longitudinal sectional, transverse sectional, top and perspective views corresponding to Figs. 36 but when the piece of furniture is used as bed. Figs. 11 and 12 show parts of the frame of the mattress in cross section and side view.

* Referring to the drawing: 1 represents the main frame of the couch-bed and 2 the top part which may be hinged to the main frame or loosely laid on to it. This top part 2 can be so constructed that in combination with the main frame a sofa, couch or any other kind of furniture is produced.

In main frame 1 mattress 4: is located, resting when the furniture is not used as bed on corner brackets 3 or other suitable devices as shown in Figures 3 to 5. Between the matan oblique angle from the ed 'es of the mat- 6 tress frame 4 to the inner upper edge of main frame 1. Instead of the bars 5 other lattice may be used.

In the form of construction illustrated as example the mattress l when to be used for the night as bed can be elevated as shown in Figures 7 to 9 so that the bed has the usual height. To prevent the bars being an impediment when entering or leaving the el'e- P vated bed they are turnably fastened to the edges of the frame of mattress l as shown in Figures 11 and 12. "When the bed is elevated bars 5 lie horizontally or nearly so, their free ends pointing towards the inner upper edge of main frame 1 and in this position they also prevent the bedding from slipping off and closing up the ventilating openings. in the horizontal or nearly horizontal position as indicated by dotted lines in Figure 12 bars 5 are held in positionby means of catches 6 or similar devices provided on the frame of mattress 4:.

The turning down of bars 5 is even then advantageous when the bed is not to be elevated for the night. In such cases it is advisable to construct one side of main frame 1 so that it can be removed or turned down, and when the bars 5 are turned down, entering and leaving the bed can be accomplished p with ease.

It is not necessary that the free ends of bars 5 press closely on to the inner sides of main frame 1, they may just as well be some distance away and the intervening space be 0 overhridged with bars fastened securely to blocirs 8 fastened to the inner sides of main frame 1. This way of elevating esiecially simple and easy to perform. fine person can do it by raising first one and then the other end of the mattress l and placing them on the cross pieces 7 put into position.

Cross pieces 7 rest during the day on brackets 9 provided on bracket blocks 8. They are provided with handles 10, and, for carrying the elevated mattress, are placed into slots 11 of bracket blocks 8, descending to the end of the downward slanting slot shown in Figure 10.

To prevent side movements of cross pieces 7 their ends are provided with guidingrings 12 running in corresponding grooves 13 of slots 11. Similar grooves are provided on brackets 9.

Side movement of the mattress 4 is prevented by collars or flanges 14% on cross pieces 7, between which the mattress lies securely. To prevent the mattress from moving in a longitudinal direction, the parts of the frame of the mattress 4L resting on the cross pieces are provided with corresponding; grooves 15.

The mode of operation is as follows: To convert the piece of furniture into a bed the top part 2 is removed. Then one end of mattress 4 is raised and the corresponding cross piece 7 placed under it, moved from its position as shown in Figure 6 to the position illustrated in Figure 10. In the same way the other end of the mattress is raised. Bars 5 are now turned down shown in Figures 7 to 9 so that they do not protrude above the upper edge of main frame 1. For converting the bed into a piece of furniture for other use the same manipulations are performed in inverted order.

I wish to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.

\Vhat I claim is:

1. In a. piece of furniture as described, in combination a main frame, a mattress frame located in the main frame on which feather beds or other bed clothing is placed,

the upper edges of the mattress frame having some distance from the inner sides of the main frame. and being some distance below the upper edges of the main frame, these distances providing ventilating spaces between the two frames, bars attached to outer sides of the mattress frame and extending upwardly and outwardly toward the upper edges of the main frame and adapted to keep the beddin lying on the mattress out of the said ventilating spaces.

2. In a piece of furniture as described, in combination a main frame, a mattress frame located in the main frame, the upper edges of the mattress frame having some KURT KOLLER.
